Title: Improvements in or relating to electric signalling systems
IPC: G08C19/00
Filed: 1925-08-23
Abstract: 240,427. British Thomson-Houston Co., Ltd., (Assignees of Hull, A. W., and St. Clair, B. W.). Sept. 24, 1924, [Convention date]. Tell-tale apparatus.-In a system for transmitting the indications of an instrument or meter such as 10, Fig. 1, to a distant point, the transmitter comprises an electron discharge device, the current through which is controlled by a magnetic field variable in accordance with the position of the instrument. As shown in Fig. 1, an electron discharge device has its filament cathode 17 and cylindrical anode 18 connected in series with a source of power 21, signalling lines 25, a recorder 26 and an indicator 24. The filament 17 is heated by current from the source 21 and a solenoid 20 wound on the exterior of the discharge device and producing a magnetic field in an axial direction is connected in series with the filament. When no magnetic field exists in the tube, the electrons flow in radial directions from the cathode 17 to the anode 18. As the magnetic field is increased, the direction of flow becomes more and more spiral, as shown in Fig. 6, until at a particular field strength, viz. the " cut-off point," the electrons are completely turned back before reaching the anode, as shown in Fig. 7, and in consequence the current in the external circuit falls to zero. The field of the solenoid 20 is adjusted to the " cut-off point " and is varied by a permanent magnet 13 which is adjustably mounted on the spindle 14 of the pointer 11 of the instrument 10. One part of the discharge device operates under " cut-off " conditions, while the other part permits a flow of electrons. The extreme positions of the magnet 13 corresponds to zero and maximum discharges respectively. Hence under the control of the magnet 13 currents having a strength dependent upon the position of the pointer 11 flow in the lines 25 and produce indications on the instruments 24, 26. A bank of lamps 22 is connected in series with the solenoid 20 and filament 17 so as to eliminate the effect of the voltage fluctuations of the source 21. Fig. 9 shows a modification in which a current proportional to the speed of an integrating meter 30 is transmitted. A damping magnet 31 is pivotally mounted on the spindle of the meter and carries a permanent magnet 13 which co-operates with the discharge device 16. The deflection of the magnet 31 which is spring-controlled is proportional to the speed of the meter. In this modification the magnet 13 swings over the top of the discharge device instead of along its side as shown in Fig. 1, and has the effect of producing a straighter deflection-current curve. Fig. 10 shows a further modification wherein the apparatus is used in place of a contact-making device for sending current impulses to a distant point. The meter shaft 35 carries the magnet 13 which influences the discharge device 16 at each revolution. The impulses operate a ratchet 36 of a registering device 37.

Abstract: 815,726. Batteries. ELECTRIC STORAGE BATTERY CO. July 17, 1956, No. 22048/56. Drawings to Specification. Class 53. Increase in internal gas pressure in a gas-tight cell during charging is minimised by introducing oxygen into the cell container prior to sealing so that the partial pressure of oxygen above the electrolyte is substantially equal to the total gas pressure within the sealed cell. The oxygen may be at sub-atmospheric pressure and may be introduced into the cell through a tube extending below the surface of the electrolyte so that oxygen is absorbed in the electrolyte. The negative electrode preferably has a greater capacity than the positive electrode and the invention is stated to be applicable to, for example, nickel-cadmium, silver-zinc, nickeliron or lead-acid cells.

Title: Improvements in method of and means for forming bellows
IPC: F16J3/04
Filed: 1951-09-24
Abstract: 722,019. Making bellows. PETERS, M. F. Sept. 24, 1951 [Dec. 13, 1950], No. 22259/51. Classes 83 (2) and 83 (4). A method of forming an annular metal bellows membrane to a concave-convex shape comprises clamping the inner and outer margins of the membrane and applying fluid pressure to stretch the unsupported area of the membrane between the margins-beyond the elastic limit of the membrane material. A membrane 1 is formed by clamping the margins 3 and 4 between the jaws 9 and 10 of a clamping device comprising upper and lower members 5 and 6 respectively which form a chamber on each side of the clamped membrane. Fluid under pressure enters the lower chamber from a duct 8. The upper chamber has a support 7, a trigger member 12 and a vent 11. The membrane is deformed until it contacts the support 7 then it is annealed and the forming pressure np applied to form the membrane. Similarly a membrane 1<SP>1</SP> is formed to a different curvature after replacing support 7 by a support 71 and the jaws 9, 10 by jaws 91, 10<SP>1</SP> and applying a forming pressure n<SP>1</SP>p. The support 71 is equal in length to support 7 plus the distance between two adjacent margins 4 and 41 (Fig. 2), and has a smaller diameter than 7 by twice the thickness of the metal. The inner diameter of the jaws 91 and 101 is equal to that of the jaws 9 and 10 minus twice the thickness of the metal. The curved surface of the membrane and the width of the margins may be varied throughout their perimeter to compensate for unequal distribution of shearing forces and bending moments induced in the membrane when they are assembled into a bellows as shown in Fig. 2. Each membrane may be formed in sections and the sections joined together to form the complete membrane.

Abstract: 1457919 Indicating apparatus; altimeters CESSNA AIRCRAFT CO 21 May 1974 [22 May 1973] 22567/74 Headings G1A G1J and G1L] An instrument providing a linear reading of a parameter from movement that is non linearly related to variations of the parameter comprises a first means subject to the movement, second means for sensing position changes of the first means, both means being initially positionable in a null position relative to each other, restoring means for relatively moving the first and second means to restore them to their null position, indicating means responding to movement of the restoring means and means, also responding to movement of the restoring means for shifting the null position. The extent of null position shift can be adjusted so that linearity is achieved. The instrument may sense pressure using the aneroid principle or temperature using a bi-metallic element, both with electro-optical second means.  Alternatively position may be sensed with an induc tive second means. The indicating means may be a pointer or, in the case of an altimeter, a radio transmitter or an autopilot. In the altimeter shown, expansion or contraction of bellows 2 moves rod 6 and slit 12 vertically. Light from source 8 passes through slit 12 and past baffle 14 on to the two elements 18, 20 of photosensitive cell 16. The light also passes through baffle 40 which comprises the null adjustment means. When the light falling on elements 18, 20 is not equal, bridge circuit 22 drives motor 24 which, via the gear train, drives rod 38 vertically (gear 36 being laterally fixed) to restore balance. Pointer 60 is also driven from the gear train. To achieve the necessary linearity, baffle 40 is moved by cam 50 and cam follower 52 to achieve the variation of the null point. The cam profile is variable by screws. In an alternative embodiment, baffle 40 may pivot instead of moving linearly.
